Scientific name: Urocerus gigas
Nature Stars: 60
About: A massive sawfly, a relative of the wasps, almost 3cm long. The female is black and yellow and has a long 'sting', which guards the ovipositor through which she lays her eggs. The larvae live in the wood of pine trees, where they spend up to 3 years. Found near pine woods, or places where pine timbers are used.
How to identify: An unmistakeable insect if seen well, perhaps only ever likely to be confused with Hornet or Hornet Robberfly.
Where: Widespread, but uncommon.
Fantastic fact: Also known as the Great Wood Wasp.
